OF FAIRMONT, MINNESOTA, A CORPORA- SLIIDING BASE IEOR BELT-DRIVEN MOTOR CARS.

Application filed January 53,

1922, Serial No.

To all whom it may concern:

Be it known that I, WALTER citizen of the United States,

Fairmont, county nesota,

F. KASPER, a resident of of Martin, State of ,Min-

have invented certain new and useful Improvements in Sliding Bases for Belt- Driven Motor Cars, is a specification.

My invention relates to of which the following a sliding base for use in connection with a railway motor car gas engine and the object to provide means pulley into car is driven,

kept taut and substantially the of the engine transmitted to wheels.

of my invention is for drawing the engine the belt through which the motor to the end that the belt Wlll. be

full power the truck Other objects of the invention will appear from the following The invention consists g detailed description.

enerally in various constructions and combinations, all as hereinafter described and partlcularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figu

re 1 is a side elevation illustrating the application of my invention to a railway motor car,

Figure 2 is a plan view, partially in section, showing the arrangement of the invention on the truck frame,

Figure 3 is a sectional view on the line 3-3 of Figure 2,

Figure dis a detail view, nection between the engine operating lever.

In the drawing,

showing the conbase and the 2 represents a pair of tubes arranged in parallel relation in bearings 3, 3 suitable means to 4 and 5 which are secured by the frame 6 of the car.

represents the engine, securely clamped to the tubes 2 by suitable me 8 and bolts 9. The tubes ans, such as straps 2 project through the forward bearings 3 and 3? and over the end of each tube I place 10 and a short slidable tube a bearing washer section 11.

Within each tube I provide a spiral compression spring 12 having plugs 13 secured therein at each 15 are mounted in these outwardly through caps ends of the tubes 2 and end and threaded rods 14 and plugs and project 16' and 18 in the 11. Nuts 17 are mounted on the rods 14 and seated against the caps 16 and wing nu ts 19 are mounted 526,765. Renewed August 11, 1922. Serial No. 581,260.

mounted on the bearing 4 and is connected with the engine base by a rod 21, turn-buckle 22, eye-bolt 23, and pin 24, the latter fitting within a pair of cars 25 on the engine base and the eye-bolt having an elongated openlng 26 therein so that the vibration of the engine will not be transmitted to the sliding base lever. When the wing nuts are tightened, the springs will be put under tenslon and the tubes moved toward the right in the sleeves l1 and engine base, being mounted on the tubes, will move in the same direction, drawing the pulley 27 mounted on the crank shaft of the engine into the belt 28 to tighten the pulley 29 that is connected with the railway car axle. In this way I am able to take up the slack in the driving belt, compensating for stretch thereof and preventing slippage when the car is in use. VVhen'ever desired, the lever 20 may be moved to the dotted line position in Figure 1, thereby pulling the engine and its pulley back, clear of the belt, and at such time the lever may be held in its dotted line position by a suitable catch provided in the opening 30 in the seat 81 on the frame of the car above the engine.

I claim as my invention:

1. The combination, with a frame, of a pair of tubes arranged in parallel relation therein, an internal combustion engine having its base connected with said tubes and provided with a pulley and belt therefor, said tubes being mounted for longitudinal movement and means for yieldingly drawing said pulleys into said belt to tension it.

2. The combination, with a frame, of tubes mounted to slide longitudinally therestationary sleeves wherein one end of said tubes is slidable, means for yieldingly drawing said tubes into said sleeves, an engine having its base connected with said tubes and provided with a pulley and belt therefor, and a lever mechanism for moving said engine and tubes and said pulley to release said belt.

3. The combination, with a frame, of tubes slidable therein, helical springs arranged in said tubes, means connecting one end of said springs with said frame, means therefor, and a lever mechanism for moving said engine base and tubes against the tension of said springs to release sald belt.

4. The combination, with a frame, of

7 tubes mounted for longitudinal movement therein, spiral springs arranged in said tubes, threaded rods connected with the opposite ends of said springs, caps mounted on said tubes and through which said threaded rods project, wing nuts provided on the threaded rods at one end of said tubes for adjusting the tension of said springs, an engine having its base connected with said tubes and provided with a pulley and belt therefor, the tension of said springs drawin said pulley into 'said belt, and means or moving said engine and tubes in the opposite direction to relieve the tension on said belt.

5. The combination, with a truck frame having track wheels and a motor mounted on said frame and provided with a. pulley and a belt connecting it with one of said track wheels, of a movable base supported on said truck frame and whereon said motor is mounted, springs for normally drawing said base in one direction to tighten said belt, and a mechanism for moving said base and motor in the opposite direction to release said belt. I

6. The combination of a truck frame having track wheels, and a motor provided with a pulley and a belt connecting it with one of. said track wheels, of a movable base supported on said truck frame and whereon said motor is mounted, means for normally drawing said base in one direction to tighten said belt, and a mechanism for moving said base and motor in the opposite direction to release said belt.

7. The combination, with a frame, of a pair oftubular guides arranged in parallel relation therein, sleeves wherein said guides are slidable, a motor having its base.connected with said guides, and provided with a pulley and belt therefor, said guides being mounted for longitudinal movement, and means for yieldingly drawing said pulley into said belt to tension it.

8. The combination, with a frame, of guides mounted to slide longitudinally therein, stationary members wherein on end of said guides is sl'idable, means for yieldingly drawing said guides into said members, an engine having its base connected with said guides and provided with a pulley and belt therefor, and mechanism for moving said engine and guides, and said pulley to release said belt.

9. The combination with a frame, of guides slidable therein, springs arranged in said guides and connected with said frame, means for increasing and decreasing the tension of said springs, a motor base connected with said guides and having a pulley and belt therefor, and a lever mechanism for moving said base and guides against the tension of said springs to release said belt.

In witness whereof, I have hereunto set my hand this 27th day of December, 1921.

WALTER F. KASPER.
